"Adaptable" scenarios were produced during play seasons one and two (2001, 2002). They featured a fairly generic setting and were intended to be modified (e.g. "adaptable") to each region where they were played. This adapting was intended to be performed by the play region organizers, not by individual Dungeon Masters. While the Adaptable scenarios themselves are fairly common, actual regional adapted versions are incredibly scare. Generally, these initial Adaptable scenarios were considered equivalent to Core or Regional scenarios.
"Adapted" scenarios, using the same ADP product prefix codes, were produced during play season six and onward. These scenarios are not complete adventures by themselves. Instead, they require the additional use of a published commercial product (generally noted by having the same title). The Adapted portion, provided by the RPGA, presented notes, errata, and changes made to the commercial product to make it suitable for Living Greyhawk convention/tournament play. While most Adapted scenarios used widely available, commercially published modules, at least one used an adventure published in Dungeon magazine.
